New build mastic in Start Hill
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. We work on windows & doors, skirting & floors and kitchens, and the jobs we see most are new-build shower sealant that has already split and cracked caulk along new skirting.
Work in a small place like Start Hill just needs the journey and access planning, and the work itself is the same as on any site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

FAQs for Start Hill
Is Start Hill in your area for new build mastic?
Yes. We work across London and the South East, and Start Hill is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Bishops Stortford station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
How long will you be here?
Most jobs take a few hours for most snagging lists, longer for a run of plots, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
How the visit works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. In a small place like Start Hill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
How to get a quote

Advice
Leave it or put it right?
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, phone 0345 464 0079 or email us with photos. Where a wall is exposed, as many are in small places like Start Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

Different surfaces, different methods
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in with baths filled first.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
When to call us in Start Hill
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry.
If you can see any of these, it’s time to have the joints looked at:
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
In and around Start Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Use the extractor fan every time you shower
- Do not wait for the house to settle if water is getting through
- Wipe joints with warm soapy water
- Keep photos and emails about snagging items
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day to cure enough for use.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Start Hill and across Essex. We can quote a run of properties together, and we’re fully insured.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What affects the quote in Start Hill
Your quote is based on your job. We look at:
- Any mould that needs treating
- Whether the work is at height
- Working hours on commercial sites
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the property is
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- Whether it has been sealed before
